Which one of the following molecules has a non-zero dipole moment A) BeCl₂ B) Br₂ C) BF₃ D) IBr E) CO₂

Question

Quizplus · Accepted Answer

IBr has a non-zero dipole moment because it is a diatomic molecule consisting of two different atoms, iodine and bromine, which have different electronegativities. This difference in electronegativity leads to an uneven distribution of electron density, resulting in a polar molecule with a non-zero dipole moment.
